Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|[8 regression] |[9 regression] |gcc.dg/nextafter-2.c fail |gcc.dg/nextafter-2.c fail --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- First of all, this test isn't present on 8 branch at all, only trunk. And, this exact testcase uses -fno-builtin and thus tests the library, so if it fails, likely your libc is buggy. Which exact subtest fails for you? E.g. replace #define CHECK(x) if (!(x)) __builtin_abort () with #define CHECK(x) if (!(x)) __builtin_printf ("bug at %d %s\n", __LINE__, #x); and see what it prints?
